Power consumption is an important parameter for the design of mixing equipment. The aim of this study is to develop a new correlation of the power consumption of a double impeller. The effect of impeller spacing on the double-impeller flow pattern and power consumption was investigated in the laminar region. As a result, the effect of impeller spacing on the flow pattern was described based on the ratio of impeller spacing to the impeller blade height. Moreover, the power consumption of a double impeller could be correlated with the same ratio.

基于层流的叶轮间距的双叶轮功率消耗相关性

功耗是搅拌设备设计的重要参数。这项研究的目的是开发双叶轮功率消耗的新关联。在层流区域研究了叶轮间距对双叶轮流型和功耗的影响。结果，基于叶轮间距与叶轮叶片高度的比率描述了叶轮间距对流型的影响。而且，双叶轮的功率消耗可以与相同比率相关。
